Filter cartridges are designed be used with our filtration rigs, to capture and remove particulates and water from oils and diesel fuels. The cartridges remove and retain any water and dirt particulates present in your fluids for easy waste disposal and longevity of your machinery.

Fluid cleanliness, particularly in hydraulic systems, is extremely important and it is widely recognised that silt particles (<5 micron in size) are a primary cause of premature machine failure through abrasive wear of component surfaces. In addition water is a major cause of system damage through accelerated oxidation, corrosion and fluid breakdown.

Our filter cartridges are rated at 3 micron absolute and - based on multi pass - will attain high cleanliness levels. The cartridge absorb all free and emulsified water and gradually removes contaminant particles down to less than ISO 16/14/11 or NAS class 5, extending the life of your oil or diesel fuel, through the removal of the oxidation catalysts and at the same time extends component life. The system can also be clean and transfer unused oil (ISO16/11) prior to use.

Filter Cartridge Range

High Visc/Cold Application (1888S)

These cartridges have a cardboard sleeve around the outside of the element and are designed to be used on high viscosity oils such as gear oils and for use on all oils and diesel fuels in very cold applications.

Filter Cartridge Maintenance

All of our filter rigs are fitted with a pressure gauge. This gauge is very important and related to the maintenance of your filter cartridges in the following ways:

On start up the gauge indicates the running pressure of the rig. With new filter cartridges the pressure will build until the bypass valve opens, once the oil has passed through the filter cartridges and expelled any remaining air, the bypass closes and the pressure will drop to a steady rating. Depending on the oils viscosity and temperature this will vary.

During filtration as the filter cartridges start to remove particles and any water, the pressure gauge will slowly rise. Eventually, the pressure will increase until the rig automatically shuts off or the fluid will create a bypass and the pressure will drop below its normal running ready.

The filter cartridges give their optimum performance when 45% to 65% full of contaminants and under average contamination around 21/18/15 conditions should give up to 250 hours of continuous use. If water is present this will significantly reduce the lifespan of the cartridges. Each filter housing and cartridge will contain approximately 1 litre of oil during operation.

If there are 2 different systems to be filtered which contain different oil grades - e.g. Hydraulic 32 and Hydraulic 46 - then there is no real reason to change filter cartridges as there would be no detrimental effect on a significant volume of oil. If however, the systems were very different - e.g. Hydraulic 32 and an automatic transmission fluids - then the filter cartridges should be changed. If you still prefer to change the filter cartridges when filtering different grades, then they may be removed carefully, stored in their plastic bags and then re-used.
